Pelargonium plant named ‘CAROLINE&#39;S CITRINE’

ABSTRACT

A new and distinct  Pelargonium  cultivar named ‘CAROLINE&#39;S CITRINE’ is disclosed, characterized by unique bright golden foliage with a green blotch in the center. The new variety is a  Pelargonium,  typically produced as an outdoor ornamental plant.

Latin name of the genus and species: Pelargonium cordifolium.

Variety denomination: ‘CAROLINE'S CITRINE’.

BACKGROUND OF THE INVENTION

The new cultivar is the product of chance discovery. The new varietyoriginated as a naturally occurring mutation of an unpatented, unnamedvariety of Pelargonium cordifolium.

The new variety was discovered by the inventor, Lance Reiners, a citizenof the United States, on Aug. 13, 2009 in the home garden of theinventor in Santa Cruz, Calif. After identifying the new variety as apotentially interesting selection, the inventor continued confidentialtesting and propagation of ‘CAROLINE'S CITRINE’ for approximately 2years, assessing stability of the unique characteristics of thisvariety.

Asexual reproduction of the new cultivar ‘CAROLINE'S CITRINE’ was firstperformed at a commercial nursery in Watsonville, Calif. by vegetativecuttings in March of 2010. Access to all plants was restricted, asplants were kept in a locked greenhouse not open to the public. Throughsubsequent propagation by vegetative cuttings, multiple generations havebeen reproduced, which have shown that the unique features of thiscultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘CAROLINE'S CITRINE’ has not been observed under allpossible environmental conditions. The phenotype may vary somewhat withvariations in environment such as temperature, day length, and lightintensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘CAROLINE'S CITRINE.’ Thesecharacteristics in combination distinguish ‘CAROLINE'S CITRINE’ as a newand distinct Pelargonium cultivar:

-   -   1. Dramatic and unique bright golden to chartreuse foliage        color.    -   2. Green markings in center of leaves.

PARENT COMPARISON

Plants of the new cultivar ‘CAROLINE'S CITRINE’ are similar to theparent, Pelargonium cordifolium in most horticultural characteristics.The new variety, however, is a slower growing plant that matures to asmaller size and produces less flowers, compared to the parent.Additionally, ‘CAROLINE'S CITRINE’ produces foliage that is brightgolden to light chartreuse with a green center blotch, compared to theparent's solid green foliage.

COMMERCIAL COMPARISON

‘CAROLINE'S CITRINE’ is similar in most horticultural characteristics tothe variety Pelargonium cordifolium ‘Donn's Goldstrike’, filedconcurrently with this application, application number unassigned. Thetwo varieties differ in foliage coloration. Whereas plants of‘CAROLINE'S CITRINE’ have foliage with a green blotch in the center,‘Donn's Goldstrike’ has foliage which is entirely bright yellow-green.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color atypical plant of ‘CAROLINE'S CITRINE’ grown in a greenhouse inWatsonville, Calif. This plant is approximately 4 months old, shownplanted in a 1 quart container.

FIG. 2 illustrates in full color a close up of the flowers of‘CAROLINE'S CITRINE.
